SBF_PARSER

A Python module to read "Septentrio Binary Format" (SBF) files generated by Septentrio receivers.

Required:

sudo apt install gcc python3 python3-setuptools python3-dev
python3 -m venv venv
source venv/bin/activate
pip install cython

Installation

python3 setup.py build

python3 setup.py build_ext --inplace

python3 setup.py install

Release Notes

• Up to 100x times faster parsing (than pure Python, thanks to Cython). Python module is written in C and complied for C-like speeds.
• All blocks documented in documentation v1.14.0 are supported.

Usage

The basic function of this module is to parse every block inside a SBF file into a map. Therefore, the dict built-in Python object is used to represent each block.

Functions

load(f_obj, blocknames=set()):

Returns a iterator/generator of SBF blocks.
f_obj should be a file object.

By default every type of block is generated, however most of the time only certain types of blocks are needed. This can be accomplished by providing a set of block names to the blocknames parameter.

Examples

Print the block name and block content:

import sbf_parser
    
with open('./dummy.sbf') as sbf_fobj:
 for blockName, block in sbf_parser.load(sbf_fobj):
  print(blockName)
  print(block)

Print the azimuth & elevation for each visible satellite using the SatVisibility blocks:

import sbf_parser
    
with open('./dummy.sbf') as sbf_fobj:
 for blockName, block in sbf_parser.load(sbf_fobj, blocknames={'SatVisibility'}):
  for satInfo in block['SatInfo']:
   print(satInfo['SVID'], satInfo['Azimuth'], satInfo['Elevation'])
